ABSTRACT

Cites the results of research indicating that tiny black holes left over from the big bang may be responsible for the high energy cosmic rays that reach Earth from extragalactic space. Notion of primordial black holes dating back to the work of Stephen Hawking and his colleagues in 1970; Form of fundamental particles taken by the black holes.

Reports on scientist Stephen Hawking's reversal of his previous argument that black holes destroy all information about matter that falls into them. Basis of Hawking's initial view; Hawking's studies which strengthens his claim that information lost from black holes leaks back out into the universe.

Features Stephen Hawking and Francis Crick, scientists who made contributions to biotechnology research. Conclusion of Hawking on black holes; Views of Crick on dreams; Problems in biotechnology research.

Theory devised by English physicist Stephen Hawking to account for apparent thermal radiation from a black hole (from which not even light can escape). It supposes that space is full of "virtual particles" in a particle - antiparticle relationship, being created out of "nothing" and instantly...

Discusses the mistake admitted by scientist Stephen Hawking regarding his stance about the possibility of using black holes to travel to other universes. Views of Caltech scientist John Preskill on the preservation of information in the black hole; Explanation for black-hole radiation, also...

The article looks at research in theoretical physics, focusing on the potential conflict between the work of physicist Stephen Hawking on the problem of information entering black holes and an experimental result reported by physicists in the Netherlands supporting the concept of quantum...

The article looks at the physics of black holes as of 2013, focusing on questions about emissions from black holes, conservation of information, and black holes' event horizon, or spherical surface. It discusses the work of theorists including Stephen Hawking, John Preskill, Juan Maldacena and...

The article focuses on black hole and white hole research. It states physicist Stephen Hawking predicted black holes would evaporate over time by emitting radiation while slowly losing mass. It mentions white holes, which are black holes that run backward in time and emit matter instead of...
